How about it gets to cold and the detectors go thru metal contraction and
cause direct short to contacts?
Thereby setting off the detectors?

Hi all, I like to heat only the rooms we spend time in during the winter
with space heaters. Now that it's getting colder I have the problem of
the household smoke detecters going off at night. It only happens in
the colder months. Anyone know why this is?

Thanks,
Rog
